Countdown to FSA Science: Week 4 Day 2

[SC.5.N.1.4] Roxana conducted an experiment to find out how the amount of salt dissolved in water affects plant growth. She had four groups of plants, each made up of two potted ferns. Roxana placed each plant group in the same sunny spot and gave the same volume of water to each group each day for two weeks. The table below shows the different amount of salt she dissolved in the water for each group.

Which of the following plant groups was the control group in this experiment?

• group a

• group b

• group c

• group d

[SC.5.E.5.1] Our home galaxy, The Milky Way, is made up of gases, dust, and ______________.

• gravity

• plants

• stars

• water

[SC.4.E.6.2] Slate is a kind of metamorphic rock. How does slate form?

• from lava that cools and hardens

• from magma that cools and hardens

• from sediment that is pressed together over time

• from other rock when heat and pressure cause changes

[SC.5.E.7.3] A city has a temperature of 750F, with partly cloudy skies. Weather forecasters are predicting that the temperature and air pressure will drop during the day. Which type of weather is most likely for this area in the afternoon?

• Rainy

• Sunny

• Snow

• Hail

[SC.5.P.8.3] Dani adds 10 grams of salt to a jar of water. She then adds 10 grams of sand to a second jar of water. She covers and shakes both jars and sets them on the table for five minutes. The materials Dani uses are shown below.

What should Dani expect to observe after those five minutes?

• Both the salt and the sand dissolved in the water.

• Both the salt and the sand settled to the bottom of the jar.

• The salt settled to the bottom of the jar, and the sand dissolved in the water.

• The salt dissolved in the water, and the sand settled to the bottom of the jar.

[SC.5.P.9.1] After filling a water bottle to the top with water, Jennifer places the bottle into the freezer for tomorrow’s field day. The next morning, Jennifer opens the freezer to find:

• The level of the water in the bottle has not changed, even though the water is now ice.

• The sides of the water bottle were pushed out and the level of the frozen water caused the top to pop off.

• The sides of the water bottle were pushed out, however some of the water remained liquid.

• The level of the water in the bottle is lower because ice takes up less space.

[SC.5.P.10.2] An object can lose some of its thermal energy. Which example below describes an object losing some of its thermal energy?

• A ball bouncing on the floor

• Eggs cooking in a pan

• Snow melting at the top of a mountain

• Water freezing into ice

[SC.5.P.13.1] A ball is sitting loose on a flat wagon that is going in the direction of the arrow. If the wagon suddenly stops, the ball will

• Also suddenly stop

• Roll forward in the wagon towards the handle

• Roll backward in the wagon away from the handle

• Bounce up and down

SC.3.L.14.1] What is the function, or role, of this part of a plant?

• It supports the leaves.

• It is where the plant makes its own food.

• It is part of the plant’s reproduction.

• It transports water to the leaves of the tree.

[SC.4.L.16.4] Both oak trees and pond apple trees produce fruit. After the fruits of these trees reach the ground, the seeds inside take root and begin to grow. What is the next stage of the life cycle of oak trees and pond apple trees?

• seed

• seedling

• flower

• adult
